The valve-coupler body has an opening that is configured over a valve stem and a seal actuator having a lever that can be rotated about a pivot with a single hand to create a seal around the valve stem. Additionally, a valve-coupler may have a gas inlet valve that can be activated by the same single hand to open the valve and allow gas to flow into the valve stem. The inlet valve may be configured in line with the lever whereby the inlet valve is opened when the lever is rotated about the pivot to contact the inlet valve. The inlet valve may be configured on the valve body for manipulation by a user's finger or thumb. The inlet valve may be on the top of the valve body.

Description

CROSS REFERENCE TO RELATED APPLICATIONS
This application claims the benefit of U.S. provisional patent application No. 62/621,046, entitled Valve-Coupler Actuating System, filed on Jan. 24, 2018 and currently pending; the entirety of which is hereby incorporated by reference herein.
BACKGROUND OF THE INVENTION Field of the Invention
The invention relates to a valve-coupler system that enables one-hand operation including coupling to and sealing to a valve stem.
Background
Attaching a valve-coupler to a valve stem takes two hands, one to press and hold the valve-coupler over the valve stem and one to actuate a lever to produce a seal with the valve stem. This operation requiring two hands is cumbersome. For example, when coupling a valve-coupler to a bicycle tire, one hand may be required for holding the tire or the bicycle, thereby making it difficult to secure the valve coupler to the valve stem.
SUMMARY OF THE INVENTION
The invention is directed to a valve-coupler system comprising a valve body and a seal actuator that incorporates a lever for one-hand operation. The lever extends below the valve body from a rocker end to a handle end. The handle end is proximal to the inlet end of the valve body and the rocker end is proximal to the valve-coupler opening in the valve body for attachment over a valve stem. The valve-coupler opening, or opening as used herein, is configured substantially orthogonally to the length axis of the valve coupler body, such as within about 70 to 110 degrees from the length axis. This unique configuration of the lever and valve-coupler opening enables attachment and sealing of the valve-coupler to a valve e with one hand.
In an exemplary embodiment, a gas inlet valve is configured along the gas conduit extending through the valve coupler body from the inlet end to the opening for placement over a valve stem. An exemplary gas inlet valve, such as a lever or body-valve, enables opening of said valve by simple pressing on the valve actuator. A body-valve may be configured on the top or side of the valve body to allow pressing and opening of the body-valve with the same hand that is used to located and seal the valve-coupler to a valve stem. One hand may be used to squeeze the lever to actuate the seal around the valve stem and the thumb may be used to press the body-valve to allow compressed air to flow through the gas conduit, through the valve stem and into a receiving body, such as an inflatable body. A lever-valve is configured on the valve body in a location such that the lever will actuate the lever-valve when rotated past a sealing angle. A lever-valve may be configured on the bottom of the valve body, below the length axis of the valve body, for example A user may use one hand to locate the opening of the valve body over the valve-stem and then squeeze the lever to actuate the seal around the valve stem. The user may then squeeze the lever further to actuate the lever-valve to allow compressed gas to flow through the gas conduit, through the valve stem and into the receiving body. When the user has filled the receiving body with a desired amount of gas, the lever can be released to rotate it back to close the lever-valve. The lever can be rotated further back to release the seal from around the valve stem to allow removal of the valve-coupler from the valve stem.
The exemplary valve-coupler of the present invention can also be used with pumps, such as hand pumps, wherein no additional valve along the gas conduit is required. The gas conduit may extend through the valve body with no valve to block the flow of gas through the gas conduit. In an exemplary embodiment, a gas inlet valve, may have an actuation mechanism or actuator that does not require continuous pressure to be applied, such as a lever or knob for example. A user may open the gas inlet valve such as by manipulating the actuator to open the gas inlet valve. The user may then inflate a receiving body with a pump, such as a hand or floor pump.
A receiving body is any reservoir for receiving air through the valve-coupler and may be a tank that is rigid or an inflatable body, such as a tire that inflates with air or gas received through the exemplary valve-coupler as described herein. Any suitable gas may be passed through the valve-couple and into a receiving body including air, noble gases such as argon, or nitrogen that is commonly used for tire inflation, hydrocarbons such as natural gas, methane or butane and the like.
A valve stem may be any suitable type of valve stem for receiving gas into a receiving body. In an exemplary embodiment, the valve-coupler is configured to seal around a Presta valve (also called Sclaverand valve or French valve). A Presta valve is a valve commonly found in high pressure road style and some mountain bicycle inner tubes. It comprises an outer valve stem and an inner valve body. A Presta valve also has a small screw and captive nut on the top of the valve body that permits the valve to be screwed shut and ensure that it remains tightly closed. The nut must be unscrewed to permit airflow in either direction. A Presta valve requires a greater pressure from the valve-coupler to open the valve within the Presta valve to allow gas to flow into the Presta valve. An exemplary valve-coupler may be configured to seal to Schrader valve, having a pin that must be pressed to open the valve to allow air flow into the Schrader valve. An exemplary seal actuator of a valve-coupler comprises a post for pressing on the pin of Schrader valve.
The summary of the invention is provided as a general introduction to some of the embodiments of the invention, and is not intended to be limiting. Additional example embodiments including variations and alternative configurations of the invention are provided herein.

For example, a process, method, article, or apparatus that comprises a list of elements is not necessarily limited to only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Also, use of “a” or “an” are employed to describe elements and components described herein. This is done merely for convenience and to give a general sense of the scope of the invention. This description should be read to include one or at least one and the singular also includes the plural unless it is obvious that it is meant otherwise.
Certain exemplary embodiments of the present invention are described herein and are illustrated in the accompanying figures. The embodiments described are only for purposes of illustrating the present invention and should not be interpreted as limiting the scope of the invention. Other embodiments of the invention, and certain modifications, combinations and improvements of the described embodiments, will occur to those skilled in the art and all such alternate embodiments, combinations, modifications, improvements are within the scope of the present invention.
Referring to FIGS. 1 to 5, an exemplary valve-coupler actuating system 10 comprises a valve body 30, and a seal actuator 15. The seal actuator comprises a lever 50 configured for one-hand operation. The valve coupler 20 has a valve body 30 that extends a length 23 along a length axis 21 from and inlet end 22 to a valve end 24. A gas conduit 34 extends from the inlet end to the valve-coupler opening 32 configured to fit over a valve stem 80. The lever extends below the valve body 30 and has a length from the rocker end 52 to the handle end 54, along the lever axis 51 that extends through the pivot 56.
As shown in FIG. 1, the lever is in an open position with an angular offset distance 57 that is large. The lever actuation arc 59 is the distance the lever can move from an open position to a completely closed position. In a closed position, the lever may be in contact with the lever-valve 72 to open the valve to allow gas to flow through the valve-coupler and into the valve stem.
As shown in FIG. 2, the handle end 54 of the lever is rotated about the pivot 56 to a seal position, wherein the seal 40 is pressed down over and around the valve stem. The movement of the lever about the lever actuation arc moves the plunger portion 58 of the lever to press and secure the seal 40 around a valve stem. The seal may be an elastomeric material having a cylindrical recess for receiving a valve stem 80.
As shown in FIG. 3, the lever is rotated further along the lever actuation arc to press on a gas inlet valve, a lever-valve 72. The angular offset distance 57 is further reduced from the open position shown in FIG. 1 and the seal position shown in FIG. 2. The lever-valve may be coupled with the gas conduit 34 and may require activation to allow a flow of gas through the gas conduit and into a receiving body 82.
As shown in FIG. 4, an exemplary valve coupler 20 is coupled to a valve stem 80 with one hand 100 and a person has positioned their thumb 102 over a gas inlet valve, a body-valve 74. The lever is in a seal position, wherein a seal is made with the valve stem 80 but the lever-valve is not opened. As shown in FIG. 5, the body-valve is activated by pressing on the body-valve to allow a flow of compressed gas to flow through the gas conduit and into a receiving body 82. A gas inlet valve may be a self-closing valve, requiring pressure on the button or actuator to maintain the valve in an open state. A gas inlet valve may comprise an actuator 76, such as a lever or knob, that can be actuated to open or close the valve and does not require continual pressure on the valve to keep it open. The actuator of a gas inlet valve may be used when a pump, such as a manual pump, is used as the gas source instead of a compressed tank gas source, or compressor. It is to be noted that a gas inlet valve, such as the lever-valve or body-valve, may be required to be activated for a flow of gas to flow through the gas conduit and into a receiving body; such as when a hand pump is coupled with the valve coupler.
